   NTM Footer (Figma redesign)

   Dark editorial footer. Brand block on the left (stacked logo +
   tagline) with a soft teal arc glow anchored to its lower-left.
   Three link columns on the right with serif column titles and
   inline social icons under "Legal". Bottom strip carries the
   copyright line and a horizontal hairline.
